## Analysis

Experiment 1

Anova Test: P value = 1.40083E-16

Bonferroni Corection: 8.33E-03

Post-Hoc Test T-Tests Corrected P-Value Is it Significant
0 mg vs. 5 mg 8.59631E-07 8.33E-03 Yes
0 mg vs. 10 mg 9.94377E-06 8.33E-03 Yes
0 mg vs. 15 mg 1.39436E-08 8.33E-03 Yes
5 mg vs. 10 mg 3.01859E-05 8.33E-03 Yes
5 mg vs. 15 mg 1.57101E-08 8.33E-03 Yes
10mg vs. 15 mg 6.4824E-08 8.33E-03 Yes

Experiment 2

T-test on the rat data: p= 0.867403497

Running an ANOVA on the rat data yields the same results:

## Summary/Discussion

Experiment 1

The p value for experiment 1 is statistically significant, as shown in the t-test and graph of the humans trials. This means that there is a significant effect of LPS on the Inflammotin protein between 0 mg and 10 mg in humans. By checking all the possible t-tests with the corrected p values, all the t-tests prove that there is a significant effect of LPS and dose.

Experiment 2

The p value for experiment 2 is not statistically significant, as shown in the t-test and graph of the rat trials. This means there is not a significant effect of LPS on the Inflammotin protein between 0mg and 10mg in rats.
